摘要	Doping Mn2+ brings in new energy levels to a variety of II-VI family and perovskite semiconductors. Although the Mn2+ luminescence in most cases appears yellow to orange, photoexcitation of the tin-based perovskite material CsSn0.9Mn0.1Cl3 (CTMC) leads to an unusual red emission at 647 nm. Characterizations using time-resolved photoluminescence (PL) and electron paramagnetic resonance (EPR) indicate that most of the Mn2+ contents in CTMC are clustered like trimer chloromanganates, which accept photoexcitation energy from the perovskite matrix and acts as emission centers. These results are in sharp contrast from Mn2+-doped CsCaCl3 or CsPbCl3, where individual Mn2+ centers dominate the PL and EPR spectra. Our results provide a new approach to broadening the color range of Mn2+ emission in perovskite semiconductors. © 2022 Elsevier B.V.
